If you hand code your pages with a text editor on a *nix box (or a PC or Mac), then there is not reason why you couldn't connect to your box via a Palm telnet or SSH client , and have at it. If what I just said doesn't register with you, then the answer is no.

smartdoc (now quickword) from http://www.cesinc.com is a great doc reader/editor right on your visor. the reason i bring it up is if you have a modem, you can upload pages directly to your server via the ftp upload menu command. i think this is exactly what you want, yes?
